If you’ve hit the limits of GitHub’s serial merge queue - main turning red, CI costs spiraling, chaos at scale - Trunk Merge Queue is the enterprise upgrade built for reliability at any scale. Handle your noisiest pipelines, cut CI costs up to 90%, and fire and forget.

​
Benefits of using Trunk Merge Queue

Trunk Merge Queue solves three critical problems that break traditional workflows at scale.

​
#1: Stop main from turning red

The problem: Flaky tests fail unpredictably. Your team mutes tests, locks branches, and gets paged to investigate. How Trunk fixes it: Failed PRs stay in queue while downstream PRs continue testing. If a later PR that includes the failed code passes, Trunk knows the failure was transient, both PRs merge together. Key capabilities:
  • Anti-flake protection with optimistic merging
  • Pending failure depth prevents cascade failures
  • Automatic quarantine of flaky tests
→ Learn about anti-flake protection

​
#2: Stop CI costs from spiraling

The problem: GitHub runs full CI for every PR. 50 PRs/day = 50 full runs. With growing teams, CI costs become seven figures. How Trunk fixes it: Intelligent batching tests up to 100 PRs in a single CI run. When a batch fails, automatic bisection isolates the culprit without ejecting the entire batch or requiring manual debugging. Key capabilities:
  • Intelligent Batching
  • Batch up to 100 PRs
  • Auto-Bisection
  • Configurable batch size & wait time
→ See how batching works

​
#3: Stop waiting in a serial queue

The problem: Single-track queue means your 2-line fix waits 45 minutes behind a slow feature PR testing an unrelated part of the codebase. How Trunk fixes it: Parallel queues create independent test lanes for non-overlapping changes. Frontend merges in Lane A while backend runs in Lane B. Native Bazel/Nx integration analyzes impacted targets automatically. Key capabilities:
  • Parallel Queues
  • Bazel/Nx integration
  • Impacted targets analysis
  • Priority merging
